1,在VS里面新建一个类库项目
2，向类库项目里添加WCF服务文件
3.按照WCF约束规范编写接口和实现类
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WcfDataSreve
{
// 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IOracleServe”。
[ServiceContract]
[ServiceKnownType(typeof(DBNull))]
public interface IOracleServe
{
[OperationContract]
DataTable GetOrderHandleData(string orderindex);
[OperationContract]
DataTable GetWorkOrderData(string orderindex);
[OperationContract]
DataTable GetWorkOrderByDate(string starttime, string endtime);
[OperationContract]
string DeleteOrderHandle(string orderindex);
[OperationContract]
string DeleteAllOrderHandle(string orderindex);
[OperationContract]
string StrConn(string index);
}
}
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.OracleClient;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace WcfDataSreve
{
// 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的类名“OracleServe”。
public class OracleServe : IOracleServe
{
public string ConnectionString { get; set; }
public OracleServe()
{
ConnectionString = System.Configuration.ConfigurationManager.AppSettings["ConnectionString"];
}
public DataTable GetOrderHandleData(string orderindex)
{
using ( OracleConnection conn = new OracleConnection(ConnectionString))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.CommandText = @"select * from M_ORDERHANDLE where ORDERINDEX = ‘" + orderindex + "‘";
cmd.Connection = conn;
cmd.CommandType = CommandType.Text;
OracleDataAdapter da = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds,"OrderHandle");
conn.Close();
return ds.Tables["OrderHandle"];
}
}
public DataTable GetWorkOrderData(string orderindex)
{
using (OracleConnection conn = new OracleConnection(ConnectionString))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = @"SELECT * FROM M_WORKORDER where ORDERINDEX = ‘" + orderindex + "‘";
cmd.CommandType = CommandType.Text;
OracleDataAdapter da = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds, "WorkOrder");
return ds.Tables["WorkOrder"];
}
}
public DataTable GetWorkOrderByDate(string starttime, string endtime )
{
using (OracleConnection conn = new OracleConnection(ConnectionString))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = @"SELECT * FROM M_WORKORDER where to_char(CREATETIME, ‘yyyy-mm-dd‘) >= ‘" + Convert.ToDateTime(starttime).ToString("yyyy-MM-dd") + "‘ and to_char(CREATETIME, ‘yyyy-mm-dd‘) <= ‘" + Convert.ToDateTime(endtime).ToString("yyyy-MM-dd") + "‘";
cmd.CommandType = CommandType.Text;
OracleDataAdapter da = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds, "WorkOrder");
return ds.Tables["WorkOrder"];
}
}
public string StrConn(string index)
{
return ConnectionString+index;
}
public string DeleteOrderHandle(string orderindex)
{
using (OracleConnection conn = new OracleConnection(ConnectionString))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = @"Delete FROM M_ORDERHANDLE where HANDLELSH = ‘" + orderindex + "‘";
cmd.CommandType = CommandType.Text;
if(cmd.ExecuteNonQuery()>0)
{
return "OK";
}
else
{
return "No";
}
}
}
public string DeleteAllOrderHandle(string orderindex)
{
using (OracleConnection conn = new OracleConnection(ConnectionString))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = @"Delete FROM M_ORDERHANDLE where ORDERINDEX = ‘" + orderindex + "‘";
cmd.CommandType = CommandType.Text;
if (cmd.ExecuteNonQuery() > 0)
{
return "OK";
}
else
{
return "No";
}
}
}
}
}
ConnectionString = System.Configuration.ConfigurationManager.AppSettings["ConnectionString"];此句读取下面创建的WCF服务中web.config的节点
4，右击解决方案添加新建网站-》WCF服务
5，更改网站信息，web.config,添加数据库访问路径节点（加粗部分）
<?xml version="1.0" ?>
- <configuration>
- <system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
- <system.serviceModel>
- <services>
- <service name="WcfDataSreve.OracleServe">
<endpoint address="basic" binding="basicHttpBinding" bindingConfiguration="LargeDataTransferServicesBinding" contract="WcfDataSreve.IOracleServe" />
</service>
</services>
- <bindings>
- <basicHttpBinding>
- <binding name="LargeDataTransferServicesBinding" maxReceivedMessageSize="2147483647" messageEncoding="Text" transferMode="Streamed" sendTimeout="00:10:00">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="2147483647" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</binding>
</basicHttpBinding>
</bindings>
- <behaviors>
- <serviceBehaviors>
- <behavior>
- <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false
-->
<serviceMetadata httpGetEnabled="true" />
- <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息
-->
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
- <system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
- <!-- 若要在调试过程中浏览 Web 应用程序根目录，请将下面的值设置为 True。
在部署之前将该值设置为 False 可避免泄露 Web 应用程序文件夹信息。
-->
<directoryBrowse enabled="true" />
</system.webServer>
- <appSettings>
<add key="ConnectionString" value="Data Source=10.192.165.144/OSMP;User ID=cnosm;Password=osm1234$" />
</appSettings>
</configuration>
6，更改WCF服务下的Service.svc文件，并把App_Code文件夹下的系统定义的服务删除
<%@ ServiceHost Language="C#" Debug="true" Service="WcfDataSreve.OracleServe" >
加粗部分为类库名.服务实现类
7，当传输数据量大或是需要控制传输量时添加红色部分代码
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
<system.serviceModel>
<services>
<service name="WcfDataSreve.OracleServe">
<endpoint address="basic" binding="basicHttpBinding" bindingConfiguration="LargeDataTransferServicesBinding" contract="WcfDataSreve.IOracleServe"/>
</service>
</services>
<bindings>
<basicHttpBinding>
<binding name="LargeDataTransferServicesBinding" maxReceivedMessageSize="2147483647"
messageEncoding="Text" transferMode="Streamed" sendTimeout="00:10:00" >
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="2147483647"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</binding>
</basicHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->
<serviceMetadata httpGetEnabled="true"/>
<!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<!--
若要在调试过程中浏览 Web 应用程序根目录，请将下面的值设置为 True。
在部署之前将该值设置为 False 可避免泄露 Web 应用程序文件夹信息。
-->
<directoryBrowse enabled="true"/>
</system.webServer>
<appSettings>
<add key="ConnectionString" value="Data Source=10.192.165.144/OSMP;User ID=cnosm;Password=osm1234$"/>
</appSettings>
</configuration>
7，右击解决方案创建WPF程序引用上面的服务
在WPF项目中右击引用-》添加服务引用-》打开页面点击发现，确认即可，
引用方法是，服务引用名.服务实现类名Client new wcf=服务引用名.服务实现类名Client();即可通过对象名引用服务接口(部分代码）
public class DataViewModel: ViewModelBase
{
public ObservableCollection<OrderHandle> OrderHandleList{get; set;}
public WCFOracleService.OracleServeClient Wcf;
public DataViewModel()
{
OrderHandleList = new ObservableCollection<OrderHandle>();
Wcf = new WCFOracleService.OracleServeClient();
DeleteSelect = new RelayCommand(ExecuteSelect, CanExecuteSelect);
DeleteAll = new RelayCommand(ExecuteAllDelete, CanExecuteALl);
}
public void QueryOrderHandle(string orderindex)
{
DataTable table = Wcf.GetOrderHandleData(orderindex);
if(table==null)
{
return;
}
for(int i=0;i<table.Rows.Count;i++)
{
OrderHandle Oh = new OrderHandle();
Oh.HandleDescrtption = table.Rows[i]["HANDLEDESCRIPTION"].ToString();
Oh.HandLelsh = table.Rows[i]["HANDLELSH"].ToString();
Oh.OrderIndex = table.Rows[i]["ORDERINDEX"].ToString();
Oh.HandlePerson = table.Rows[i]["HANDLEPERSON"].ToString();
Oh.HandLetype = table.Rows[i]["HANDLETYPE"].ToString();
Oh.HandleTime =table.Rows[i]["HANDLETIME"].ToString();
Oh.HandleStatus = table.Rows[i]["HANDLESTATUS"].ToString();
Oh.Select = false;
OrderHandleList.Add(Oh);
}
}
8 发布至IIS
（1）.把整个WCF服务文件拷贝至服务器中
（2）找到服务器中IIS管理器找到网站，新添加一个网站，配置基本信息，
（3）配置完成后，点击IIS右侧浏览网站-》点击Service.svc,拷贝如下地址到添加服务引用的页面即可找到，并引用
svcutil.exe http://IP地址和端口号
/Service.svc?wsdl
